St. John's Episcopal Church is a seasonal church in Harbor Springs, Michigan, and a part of the Episcopal Diocese of Western Michigan.

St. John's Episcopal Church first met in 1878, three years before the City of Harbor Springs was incorporated. In 1881 a lot was acquired at Third & Traverse Streets, on which a new church building would be built. On July 19, 1883, St. John's Episcopal Church was consecrated.

Today, St. John's is a summer parish of members and visiting clergy from throughout the United States, who provide year-round financial support to the Northern Michigan Community.
